Is he allowed to fly the flag in some other fashion?
Flagpoles aren't the only way US flags are authorized to be displayed.
My mom just moved to a retirment village, a condo as opposed to one of the stand alone villas the also have. This is the first time in her adult life that she's lived at a place where she has to abide by their rules.
They don't seem that restrictive, but when I mentioned that when it came time to wash her screens I thought I'd just bring over a power washer and do it there, she told me that's something that probably couldn't be done. So, we'll have to bring the screens over to somebody's house to do them, or else pay the HA $5 a shot to wash them.
The hell with that. Paying to have them washed, that is.
